IMPROVEMENT IN SUMMER-FURNAGES.

ro ALL WHOM Ir MAY coNcERN.

Be it known that we, EznKIEL C. LITTLE and JAMES W. BELL, of the cityand county of St. Louis, State of Missouri, have invented a new anduseful Improved Charcoal-Furnace, of which the following is a full,clear, and exact description, reference being had to the annexeddrawing, constitutingn part of this speeiiication, in which i Figure 1represents a front elevation of our invention. Figure 2'represe`uts atop view of same, and Figure 3 represents an end view of same when inposition for use, and having a portion broken out to show the port forthe back draught. s

Similar letters indicate like parts.'A v Our invention contemplates acharcoal-furnace, to be used in connection with an ordinarycooking-stove,- whch'shall eeonomize fuel and throw out but little heatinto the room. v

It consists of a cast-iron basket, A, figs'. 1 2, and 3, with agrate-bottom, as shown at B, iig. 2, and having ports 1, 2, 3,4, 5, 6,7, 8, 9, and 10, g. 1, in the front, and two .long ports e e', iig. 2,and c, iigfS, in the back. To' the bottom of thc basket is attached'ahinged plate, el, igs. 1 and 2, which, by means of a catch e, fig. 3,falling into one of the back ports, is kept in the position, shown intig. 1, close against ythe basket. The front top of the stove beingtaken effin the usual way, the basket, by meansl of the handle z, figs.1, 2, and 3, may be placed in the fire-box o of the stove, and as itsettles to position, the jar will cause the plate d to fall down, till,striking against the fire-back, it assumes the position shown in fig. 3,thereby preventing any draught passing in thatdirection.) The dempers'of the :stove and also the front doers, ii'` there be any, beingopened, all the draught passes throughthe basket from side to side, orfrom the bottom up and through the back,- in the direction indicated bythe ar1'ow7c,g. 3. The draught that would -pass under the basket and upthe chimney is turned back by the plate d, and forced t0 pass throughthe basket before escaping. A grate may be placed in the basket to restirons upon, or the plate m',g. 2, may be4used, 1ivirlin|g` it into tw-oparts for kettles and other cooking-utensils. 4

The advantage of our invention consists in having'an upward draught frombeneath and thesides,k instead of a downward draught, as is the casewith other furnaces of this kind. The heat, instead of being carriedaway from the top of the grate, as it must necessarily be when thedraughtis downward, is, by our invention, brought i .to bear directly atthe point where most needed, and all the heat is utilized, since none ofitcan pass away, save through the basket, o n account ofthe plate d.

We do not claim to be the rst inventors of a furnace to be used with acooking-stove; but What we do claim as our invention, and desire tosecure by Letters Patent, is-'- The construction of-ehareoal-fnrnace,having a hinged plate, d, at the back thereef,'wlziel1, shutting off thedraught from beneath, causes it to passup through the basket. f
